Abstract (en)
[origin: EP3269437A1] An extraction sheet having high machinability in the manufacture of an extraction filter for beverages and an extraction filter using the same and having high handling property is provided. The extraction sheet comprises a layer including a meltblown nonwoven fabric that is formed from fibers of a polylactic acid-based resin having a crystallinity of 9.0% or lower and a fiber diameter of 15.0 µm or smaller and that has a basis weight of 2.0 to 30.0 g/m2, and a layer including a spunbonded nonwoven fabric that is formed from fibers of a polylactic acid-based resin having a crystallinity of 30.0 to 60.0% and a fiber diameter of 35.0 µm or smaller and that has a basis weight of 5.0 to 30.0 g/m2. The extraction sheet has a bending hysteresis of 5.0×10 -3 to 14.5×10 -3 gf·cm/cm.
